GENERAL DESCRIPTION

The MSM63P180 is an M6318x series one-time-programmable ROM version product of OLMS-63K family, which employs Okis original CPU core nX-4/250.

The MSM63P180 has one-time PROM as internal program memory.

The MSM63188 and other mask ROM-version products have mask ROM as internal program memory.

The specifications of the MSM63P180 are equal to those of the MSM63188 except for electrical characteristics, packaging, and some functions.

The MSM63P180 is used for evaluating the software development of M6318x series products.
